New SMOS Level 3 salinity products available

26 May 2017

New salinity products are available at CATDS (Centre Aval de Traitement des Données SMOS).

A new correction for systematic errors (land-sea and seasonal-latitudinal) has been implemented in CATDS CPDC and in CATDS CEC LOCEAN.

Concerning CATDS CPDC, a RE05 reprocessing of ocean salinity is available from January 2010 to March 2017; the operational processing has been updated accordingly. Binned maps at the usual spatial and temporal resolution are available. The SMOS SSS corrected for systematic errors are in MIR_CSQ3 files; non corrected SMOS SSS remain available in MIR_CSF3 files.

The corrected product is limited to 45N-47S, the correction remaining uncertain at higher latitudes.

A new ATBD is available to download.

Concerning CATDS CEC-LOCEAN, 9-day and 18-day products sampled at 25km resolution are provided every 4 days. They cover all latitudes from January 2010 to December 2016. CATDS have documented this in more detail.

A validation of these products was presented at the European Geosciences Union (EGU) in April - the poster is available to download.

Further information and the FTP sites for both products can be found on the CATDS website.
